摘要
为准确描述重金属粉末嵌层碳纤维复合材料(CFRP)壳体静爆下对人员目标的毁伤效应,验证其低附带毁伤特性,着重分析重金属颗粒群、爆轰产物、冲击波前沿三者间的时程关系及相互耦合作用下的终点毁伤效应。结合理论分析和试验研究,获得了重金属粉末嵌层CFRP壳体战斗部等效简化结构模型。在Visual C++语言基础上,采用二维数值模拟程序和Tecplot后处理软件,分析爆轰驱动过程中不同装药条件对粒子、爆轰产物和冲击波前沿时程关系的影响规律。结果表明,颗粒追赶距离随密度增加而增加,随着颗粒质量分数增加,粒子追赶冲击波和爆轰产物的距离增大。
In order to accurately describe the damage effect of heavy metal powder embedded carbon fiber reinforced plastic( CFRP) shell on the personnel target and verify its low collateral damage characteristics,the time-history relation and mutual coupling of heavy metal particles,detonation products and shock front and the end-point damage effect are emphatically analyzed. Based on the theoretical analysis and experimental study, an equivalent simplified structural model of heavy-metal-powder-embedded CFRP shell warhead is established. On the basis of Visual C + + language,two-dimensional numerical simulation program and Tecplot post-processing software are used to analyze the influence of different charge conditions on the detonation process and the frontier time-history relationship of particles,detonation products and shock wave. The results show that the particle catching distance increases with the increase in density,and with the increase in particle mass fraction,the distance of the particles catching the shock wave and the detonation product increases.
